BRACE FOR KNOCKDOWN FURNITURE.

SPECIFICATION forming part of Letters Patent No. 636,434, dated November7, 1899; Application filed December 20, 1898. Serial No- 699,846. (Nomodel.)

To all whom it may concern:

Be it known that 1, DAVID W. KENDALL, a citizen of the United States,residing at Grand Rapids, in the county of Kent and State of Michigan,have invented a new and useful Brace for Putting Up Chairs, &c., in theKnockdown, of which the following is a specification.

My invention relates to braces to place in the corners of chair, settee,and other furniture frames to securely hold the parts to place withoutthe use of glue; and its objects are, first, to provide a brace thatwill hold the frame securely and firmly together and at the same timeadmit of its being readily taken to pieces for shipment, and, second, toavert the danger of the frame becoming loose-jointed by'reason of longand constant usage. I attain these objects by the mechanism illustratedin the accompanying drawings, in which Figure 1 is a plan of achair-frame with the seat removed and the posts shown in section tofully illustrate the manner of applying my brace; and Fig. 2 is aperspective of the brace, made upon a larger scale to more fullyillustrate its construction.

Similar letters refer to similar parts throughout the several views.

In the drawings, A represents the side rails of a chair. A representsthe front rail, and A the back rail, of the same, and B represents mybrace. This brace is constructed substantially of the form shown, havinga dovetailed rib on one surface, which rib is designed to pass into acorresponding slot in the side rails of the chair-frame, as indicated atb in Fig. 1. The opposite wing of the brace is provided with one or moreapertures, as I), through which bolts may be passed, as indicated at bin Fig. 1, to secure them to the back and front rails of thechair-frame. The dovetailed rib I) should be made to fit the groove inthe rails very closely, so that there will be no danger of the shrinkageof the wood or-of continual use of the chair causing it to get loose,and the angle of the brace must be less than the angle of thechair-frame, as indicated by the open joint between the wings of thebrace and the front and back rails of the frame in Fig. 1, so that toscrew the bolts 1) firmly to place will cause the rails to spring inconsiderably, as indicated by the dotted lines of the side rails in Fig.1, which has a double effect-first, to draw and hold the ends of therails firmly against the posts, and thus insure perfect joints, and,second, it averts all danger of the frame becoming weak and shackly fromconstant use.

I prefer that the rib b be madeatrifle wider at the top than at thebottom, so that it may be wedged snugly into the groove in the siderails of the frame.

For the purpose of averting the necessity of leaving the head of thebolt b exposed at the front surface of the front rail of the chair I usea joint-bolt and insert its head in a groove in the rail, as indicatedby the dotted lines at the ends of the rail A, in the usual manner ofinserting joint-bolts.

Having thus fully described my invention, What I claim as new, anddesire to secure by Letters Patent of the United States, is-

In combination with the rails and posts of a chair or other furnitureframe, an angled body, a dovetailed rib on one wing of said body,arranged to engage a dovetailed groove in the side rails, the angle ofsaid body being less than the angle of the frame, and the angle cornercut away so that it may connect the rails without touching the post, andbolts for securing the opposite Wings of said body to the back rails ofthe frame, the angle of the brace being such as to spring the rails ofthe frame, substantially as and for the purpose set forth.

Signed at Grand Rapids, Michigan, December 13, 1898.

DAVID IV. KENDALL.

In presence of- AUGUST BEHRENS, ITHIEL J. CILLEY.
